Open Source C Algorithms for Mac - Page 5

A simple (~20 line python) O(n^6) algorithm for the traveling salesman problem that seems to do pretty well for most graphs; so well that I have not been able to find a graph which it does optimally solve. Those with spare cycles are welcome to help out.

This project has moved to github at http://lmwtree.devries.ninja.

Libcutils provides a self-contained set of fundamental routines which are essential to basically any Unix utility or daemon application written in C. The library provides fundamental data structures such as lists, hash-maps, strings and parsing functions for JSON or the typical dot-file based configuration data. The following list summarizes the currently supported functionality: * length delimited instead of NULL terminated strings * memory management based on reference counting * several list processing functions like iterators and map-reduce * support of [Ideal Hash Tries](http://infoscience.epfl.ch/record/64398/files/idealhashtrees.pdf) for highly efficient hash map data structures * parsers for [JSON](http://json.org) data and the text configuration files found in Unix system * doubly linked circular lists for reliable event queues * support for test and debugging of memory management problems such as memory leaks

Library for calculating fields of view and lighting on low resolution rasters, suitable for roguelike games.

A powerful hashing library with features like dynamic bucketsize adjustments, thread safety, generic interface, rbtree bucket storage and a bundle of hashing algorithms.

A library for lzw arithmetic. It is used to encode/decode the specifical stream.

A library written in C for lossy image compression. Library libopen/format OPEN supports two methods of compression - discrete cosine transform (used in JPEG) and discrete wavelet transform (used in JPEG2000).

Lightweight prime number generation library. Makes use of OpenMP and aims for performance. Suitable for applications in cryptography or just for educational demonstration.

A library of standard data structures in C, similar to STL in C++. Includes variable-length arrays, deques, hashtables, avl trees, binary heaps, and many other useful structures, with a simple and intuitive interface.

Libtdata is a small and portable C library implements a set of various search data structures, bit operations and index allocation.

a simple software implemented FPU. only 32bit precision is supported and the operation result is not accurate as modern FPUs, but it is light and compact. (uses simple 32bit integer operations only, good for machines that has no hardware FPU.)

Matho is a OS Independant Application and API for mathematical operations, features include curve sketching, calculus, iterative formulae, algebra solver, 2d/3d geometry and mechanical and statistical functionality.

A portable in-place bitwise binary Fredkin trie algorithm which allows for near constant time insertions, deletions, finds, closest fit finds and iteration. Is approx. 50-100% faster than red-black trees and up to 20% faster than O(1) hash tables.

Palex is a two-stage biological sequence searching system. Library will contain functions for searching patterns, palindromes and structures in DNA sequence.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

pycrc is an easy to use CRC (cyclic redundancy check) calculator and C source code generator. The generated source code can be optimized for simplicity, speed or space. pycrc contains a long parameter list of common CRC models. The program is self contained and does not require installation. Apart from a python installation, it does not require other libraries to be installed.

small QT Programm for Testing my recursive Algorithm for calculation the bitreverse of a single number in a series with Length: 2^X with X=Number of Bits

reputron is a knowledge extraction engine platform that covers all aspect of text mining, relevance, indexing and querying on a corpus of text documents.

A Ring-Buffer instance could be used with element types - char - long - long long - void* . Focus is on a hardened SW structure with buffer-instance-pointer check (not very fast but more secure). Some features are globally choosable on compile-time (e.g. switch multithread support off completely to have faster access). Note: User Interface is for Test and Tutor Code only.

This project is no longer supported by its creators. salgo is a C framework you can use to implement sorting algorithms. It provides different ways of filling an array and then sorting this in ascending or descending order (a stop watch is included).

This library is a lightweight implementation of genetic algorithm, contains the most popular types of chromosomes and the basic algorithms for selection, elitism, crossing and mutation.

breve is a free, open-source 3D multi-agent simulation package designed for simulating decentralized systems and artificial life.
